the problem is that people assume that life requires conditions like ours to survive. we have found life in vocanos, deep sea vents, deep sea trenches where there is zero sunlight, and inside glaciers. we have even found fossils of bacteria on meteorites.

research continues to point to the abundancy of life, and how common simple lifeforms are. its likely there are simple forms of life MANY places in this solar system, and new photos of mars indicate large patches of what is hypothesized to be organic matter (fungus, or bacterial life, i think it was).

now, inteligent life? thats probably ALOT more rare. and will we ever find any? who knows. it would require vast amounts of energy to travel between stars in a timely fashion, and by the time we have that much energy available, we should be able to manipulate matter danm near any way we want. once we have some form of 'limitless' energy, and technology to manipulate matter on a subatomic level (on a mass scale, unlike how we can do it now on an individual scale) we should be able to take advantage of the matter in the local solar system to create just about anything we want.

the only compelling reason to travel out of the solar system is to satisfy exploratory curiosity, or to avoid a dying sun. and once we have the technology to leave, we should be able to survive anywhere where we can find solid matter to consume. maybe even in deep space.

so the only possible reason aliens would find us, is if they were HIGHLY advanced, far beyond the typical sci-fi depections of aliens, and if they were trying REALY HARD to find us.
